I own an iClear 30B, a MPT3 and 2 Twisp Clearos and I have to say out of all these 3 brands my Twisp Clearos have given me the least trouble with regards to spitting, gurgling, flooding and cleaning. I have so many problems with my MPT3 that I have to keep the Twisp Clearo as a standby unit. My iClear 30B seems to mute flavours so I don't reallt get mych out of it, whilst my MPT3 has a fantastic taste - still, these units are a PITA when it comes to maintenance. Anyone else feel the same?
